Edge data storage and integrity verification method based on trust value and erasure code

The invention requests to protect an edge data storage and integrity verification method and system based on a trust value and an erasure code, and the method specifically comprises the steps: calculating a trust value and a capability value of an edge server through a cloud server, and selecting a storage server, a storage verification server and an integrity verification server; and based on the selected result, the intelligent terminal processes and sends data, the storage server stores the data, the storage verification server verifies the storage result, and the integrity verification server detects the data integrity. According to the method, the trust value and the capability value of the edge server are considered, the reliability of the edge server in the data storage process is improved, and the data integrity is ensured; the intelligent terminal only performs a small amount of data processing, so that the energy consumption of the intelligent terminal is reduced, and the data processing time of the
